Specification of 'Izetters'Patent.

Patented Mar. 30, 1915..

Application filed November 25, i913. serial No. 803,037.

TofdZZ whom it may concern:

Be .it lmown that we, PHiLIP H. Voie'r and 'OsoAR C. Kuniinn, citizens of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new -and useful WindingDrum, of which the following is a specification.

The present application relates to improvements in winding drums, the same being especially adapted to be used in con nection with the winding drum shown in our co-pending application filed September 3, 1913, Serial No. 788,030, one object of the present invention, being the provision of coep'erative means carried by the support "for the axle and the drum, and one head of thedrum, whereby the head is permitted the desired oscillatory movement at the begin ning of the rotation of the drum in a for- Ward or reverse direction, whereby the posi tion of the cam for imparting the longitudinal sliding movement to the staves or the drum is changed relatively to the standard and whereby the offset portion of the cam is thus placed in the proper positionfor reeling or unreeling the cable upon or oil of the drum during the winding or unwinding action of the drum.

A further object of the present invention, is the provision of a cam carrying member disposed for oscillatory movement in connection With the standard which supports the drum provided with a plurality of longitudinally slidable staves, whereby the relative position of the cam may be changed to properly oscillate the staves to guide the cable to and from the drum during the winding and unwinding action of the cable, such action of the cam being automatic and operated entirely due to the stress or pull placed upon the cable.

WVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosedca'n be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a longitudinal seeuqnn view through a complete druinand support. Fig. 2 is'a section taken onlmeis a r Fig. 1. Fig. 3 is a diagramin'atic plan view of the periphery of the cam carry ng member showing the shape of the cam slot for actuating'the s'taves of the drum. ig. 4 is aside elevation of one of the stavespe'rfe. Fig. 5 is a detail view of an anti-'fri ctionally supported stave.

Referrin to the drawings, the numeral 1 designatesthe' standard or hanger which has rotatabl'y ineunted therein, the drum carryshaft 2, the head or member 3 being rotatably mounted upon the shaft 2 independently of the hanger 1 and 'ha'ving the bearing sleeve 4: for properly supporting the same. The rim 5 constitutes a housing connection with the outer periphery of the cam carrying member 6 for the inner ends of the longitudinally slidable staves 10, said ca'in carried member being movable with the member 3 due to the fastening thereof means of the screws 'or bolts 7.

The periphery of the cam carried member is concentric with the inner face of the 'fiangeor rim 5 of the member 3 is provided with the 'cam slot 8 for thereception of the anti frictional rollers 9 mounted one to each stave 10, so that as the shaft 2 is rotated, the sleeve 12 which is keyed by means of the screws 13 to the shaft 2 will cause the rotation of the disk 11 to which are mounted and connected for sliding longitudinal movement, through the instrumentality of the ribs 10, the staves 10 which constitute the cable receiving portion of the drum. Thus the staves are properly rotated, and as the cam carried member 6 is held stationary with regard to the drum, the staves 10 have imparted thereto, the desirable longitudinal movement to cause the guiding projections 18 for the 'cabl'eto he moved in the proper position for guiding the lead on or of? strand of the cable to and from the drum.

The head forming member ll of the drum, is connected by means of pins 15 to the spool 12 so as to rotate with the shaft 2, the inwardly projecting rim 16 providing a housing for the outer ends 17 of the staves 10 so that there is no possibility or the ends of the stav'e's becoming entangled with the cable.

In order that the member 3 and consequently the cam carried member 6 may be automatically oscillated relatively to the standard 1 and shaft 2, and consequently the stave carrying member 12, so as to place the operating portion 8 of the cam slot at different positions due to the'unwinding and winding of the cable upon the drum, the member 8 is provided with a plurality of threaded sockets 19 for the reception of the pins 20 and 21, the standard 1 being provided with the pin 22 disposed in the path to engage either one of the pins 20 or 3.1 and thus limit the distance of oscillation of the member 3 and its cam carrying member 6.

A plurality of the threaded sockets 19 are provided so that the pins 20 and 21 may be positioned to permit of the members 3 and 6 being oscillated to a greater or less degree, the illustration shown in Fig. 2 permitting the members to oscillate two-thirds of arevolution while with six sockets shown, the smallest movement would be one-sixth of a revolution. 1

As shown in Fig. 5, the staves 10, are each provided with a rib 1O which corresponds to the ribs 10 heretofore described. A recess 10 is provided in the under side of the rib for the reception of the balls 23, which constitute a ball bearing support to permit of the easy longitudinal sliding of the stave. The balls 23 slide within the respective grooves 24 formed in the outer surface of the periphery 25 of the drum consisting of the disks 11*, said disk 11 corresponding with the disks 11, but being connected by means of the plate 25 as shown. By this means, the grooves 24: lock the staves 10 against circumferential movement, but permit the desired longitudinal sliding movement due to the cam 8.

This structure is especially adapted in connection with the use of large drums, and also wherein the strain upon the staves during the winding and unwinding would be such as to bind each individual stave and render it difficult to produce the longitudinal sliding action necessary.

WVhat is claimed is: v

1. A winding drum, including a support having two heads, a cable receiving member journaled between the heads and having a plurality of longitudinally slidable staves, the ends of which are housed within the heads, a section of a cable guiding flange carried by each stave, one head being provided with a cam groove, and means carried by the adjacent end of each stave for engaging the cam groove, whereby as the drum is rotated, the staves have successive longitudinal sliding movement imparted thereto.

2. A winding drum including a support having two heads, a cable receiving member journaled between the heads and having a plurality of longitudinally slidable staves,

the ends of which are housed withinthe staves, keyed to the shaft, the ends of the staves being housed within the heads, a section of a cable guiding flange carried by each stave, an annular member seated within the recess of one head and provided with a cam groove, and a projection carried by each stave for fitting in the cam groove,

whereby as the drum is rotated, the staves have successive longitudinal movement imparted thereto.

i. A winding drum, including a support,

a shaft rotatably mounted therein, a cable receiving member having a plurality of longitudinally slidable staves keyed to the shaft, a cam for actuating the staves to im-. part longitudinal movement during the rotation of the shaft and staves, an oscillatory member upon which said cam is formed, mounted upon the shaft and in engagement with the staves, and cooperable means carried by said member and the standard for limiting the oscillation of the cam carried member and for varying the position of the cam relatively to the standard.

5. A winding drum, including a standard, a shaft rotatably mounted therein, a cable receiving member keyed to the shaft and having a plurality of longitudinally slidable staves constituting the cable receiving surface thereof, a cam carrying member mounted for oscillation upon the shaft adjacent one end of the staves, meanscarried by the staves for engaging the cam whereby as the shaft is rotated, the staves have imparted longitudinal movement thereto, and cooperative means carried by the cam carried member of the standard for limiting the oscillation of the said member during the winding and unwinding rotation of the drum, whereby the position of the cam is automatically shifted.
